Am I missing sonething? Looks like the Honeywell 270 would draw about 460 amps daily from your 12v battery bank if run around the clock. That means it would discharge 10 6v 220-amp deep-cycle golf cart batteries by just less than 50% daily, so long as they are fully recharged each day. That is about as far as you can go without damaging the batteries.
To fully recharge that size battery bank on clear days that are fully sunny between 10 a.m. and 2 p.m. would require more than a kilowatt's worth of 12v solar panels -- 11 100-watt panels would probably do it. (Multiply your panel's rated wattage by four and that is roughly what you can expect it to produce daily, on average, year-round on clear days, based on my just short of 30 years of real-world experience with solar in the Southwest. Late summer in Nevada you might get 10% to 15% more than that.) That is a lot of equipment and weight to haul, and a lot of expense to go to, in order to run a $200, 230 watts per hour commercial swamp cooler efficiently. And then, with the Honeywell's design, you still face the challenge of how to draw in and exhaust 270 cubic feet of air per minute. Evaporative cooling only works well so long as you are drawing in fresh dry air and exhausting stale, damp air at roughly the same rate. I question the practicality of using the Honeywell 270 unit on the Playa.

Thanks for posting., Do you dare post it on Figjam's ePlaya thread about swamp coolers <https://eplaya.burningman.org/viewtopic.php?t=33842>, or do you think that's just asking for unkind comments On Wednesday, July 25, 2018 at 7:23:58 PM UTC+2, Steve Upstill (Swifty) wrote: Kevin Fischer <kfisc...@gmail.com>: Jul 27 02:57AM -0700 I admire the DIY attitude but it should be more widely known that mass manufactured swamp coolers are available on Amazon Prime and the $200 one will evaporate more water than you probably want to give it if you run it on high and is overkill for an H12. https://www.amazon.com/SPT-SF-614P-Evaporative-Cooler-Cooling/dp/B00TRLXXWA/ref=sr_1_17?s=home-garden&ie=UTF8&qid=1532685161&sr=1-17&keywords=swamp+cooler is what I used last year and it kept me sleeping in till 2PM without fail. You can build more airflow for the price yourself but perfectly lining up the evap pads is hard and nothing hand build will be as well sealed as what you can buy online.

Jay Batson <batson...@gmail.com>: Jul 27 12:21PM +0200 Kevin - The general setup is to put the swamp cooler outside the yurt / tent, and vent it inside. I don’t see how to do this with that Amazon unit. Have you tried putting that unit inside the structure to be cooled? Is the net temp change good? -------- Jay Batson batson...@gmail.com <mailto:batson...@gmail.com> Mobile: +1-978-758-1599 Blog: http://startupdj.com <http://startupdj.com/> Twitter: @jab <http://twitter.com/jab> Schedule time to meet or talk <http://doodle.com/batsonjay> Back to top <#m_-6741504196040149180_digest_top> You received this digest because you're subscribed to updates for this group.
